HOLDER FOE BAGS DURING FILLING OPERATION.

The present invention relates to an improved holder for bags,particularly adapted for use during the filling of the same.

The invention has for its object to provide a simple device, the costofmanufacture of which is reduced to a. minimum; one which when used willincrease over the old method the number of bags filled and at the sametime reduce the cost of labor by eliminating the workman necessary withthe old method for holding the bag upright with its mouth open; onewhich will retain the bag in an upright position and maintain the mouthfully open and its body in aspread condition for filling; to provide adevice capable of fitting any bag, and one which can be readily foldedfor storage purposes when not in use, or for initially positioning thedevice within the bag, for subsequent unfolding to spread the bag bodyand mouth and to retain the open bag in upright position for fillingpurposes.

With the above mentioned and other objects in view, the inventionconsists in the novel construction and combination of parts hereinafterdescribet, illustrated in the accompanying drawings and pointed out inthe claim hereto appended; it being understood that various changes inthe form, proportion, size and minor details of construction within thescope of the claim may be resorted to without departing from the spiritor sacrificing any of the advantages of the invention.

Reference is directed to the accompanying drawings, wherein Figure 1 isa view in perspective of one embodiment of the invention. in operativeposition, the bag being illustrated in dotted outline.

Figure 2 is a view in detail of the upper ends of the side members andthe hinged connecting member uniting the same.

Fig. 3 is a view of the bag frame in folded position.

In the drawings wherein like characters of reference designatecorresponding parts, the numerals 1 and 2 indicate inverted U-shapedframe members preferably of hollow tubular material, the parallelportions of said frames constituting legs 3 and 4 adapted to rest on thebottom wall 5 of the bag 6 when in-' serted therein. Corresponding legsof the frame members 1 and 2 are connected preferably near their upperends by a'uniting frame 7, the ends 7 of which are pivotally connectedwith the legs 4 of the frame members 1 and 2, as shown at 8, thuspermitting swinging movement of the frame members land 2 at the outerends of the uniting frame 7. The uniting frame 7 is centrally hinged at9, enabling said frame members to flex inwardly, permitting the framemembers 1 and 2 to lieadjacent to each other,

as shown in Figure 3 of the drawings.

Any. means may be employed to maintain the ends 7 of the uniting frameconnected with the frame members 1 and 2, the preferred means being pins10 passing through the legs 4: between which the frame ends 7 lie. Tolock the uniting frame 7 in open position. a latch 11 is provided, oneend 12 thereof being pivotally mounted at one side of the hinge 9 andthe free end being hooked hinge, thus locking the members of the unitingframe in alignment.

In operation, with the uniting frame preferably folded, the framemembers are inserted within the bag 6 with the legs 3 and 4resting uponthe bottom. wall 5 of the bag, the uniting frame 7 is then operated toextended position and locked. The frame members 1 and 2 are then swungon their fulcrum connection at the ends of the uniting frame until theforward legs tightly engage. the front wall 5 of the bag, as shown inFigure 1, thus holding the bag walls taut and the bag in an openposition during the filling operation. When filled, the uniting framemay be collapsed, the bag frame members may be swung on their fulcrumconnections and the structure withdrawn from the bag, as a unit, and thetop of the bag closed for shipment.

The lightness of the structure enables the bag filler to readily handlethe same, both in inserting it into a bag to be filled, removingit froma filled bag or folding it for storage purposes. By the employment ofthis frame, the bag filler can readily lift, shake the bag to settle itscontent while the frame isrin position as the top portions of the framesafford gripping surfaces and with a port-ion of the bag mouth gripped ineach hand, there is no liability of the frame pulling from the bagduring the settling operation.

I claim A bag filling frame comprising a pair of bag spreading framemembers, each consisting of parallel leg members united at least at oneend by transverse members, said frame members adapted for insertionwithin the at 13 to engage on the other side of the bag to be filled,with their united ends upwardly disposed, a hinged uniting framehingedly connecting at its ends correspond ing legs of said bagspreading frame members near their point of connection, said bag areadapted for swinging to lie parallel 10 with the hinge of said unitingframe when the frame is in folded position, or at right angles theretowhen the frame is in extended posltlon.

In testimony whereof I have signed my 75 name to this specification.

JOSEPH D. COX.
